A good daily multivitamin containing zinc, vitamin B, folate, iron, and calcium is a very reasonable choice. Newer studies suggest that vitamin D may be somewhat helpful and worth considering. Specific vitamin and mineral deficiencies like iron or vitamin B12 may be diagnosed by blood tests and treated.
Multiple vitamins including biotin have been promoted for hair growth, but solid scientific studies for many of these claims are lacking. While taking biotin and other supplements marketed for hair, skin, and nails probably won't worsen anything, it may also not necessarily help the situation. Therefore, advertised hair-regrowth supplements should be approached with mild caution.
Can itchy scalp cause hair loss?
Itchy scalp may cause mild, reversible hair loss. Causes may include seborrheic dermatitis (dandruff). Treatments may include medicated shampoos like ketoconazole (Nizoral) and topical cortisone creams and lotions to help decrease itching.
How do I prevent hair loss?
Hair loss prevention involves several factors depending on the underlying cause. Good hair hygiene with regular shampooing is a basic step. Good nutrition, especially adequate levels of iron and vitamin B, is helpful. Treatment of underlying medical conditions like thyroid disease, anemia, and hormonal imbalances may useful in prevention.
